Application filed February 20, 1919. Serial No. 278,126.

invention, such as will enable others skilled in the art to which use the same.

My invention has for its principal object to provide a comparatively'simple and inexpensive, yet a highly efficient, reliable and convenient mucilage brush which may be easily carried in the users pocket without requiring any more space than an ordinary fountain pen.

In carrying out the above object, other objects are to provide an easily projectable it appertains to make and and retractable brush for applying the muci-l lage; to provide a novel ymountlng for the presser bar which compresses a tube of mucilage in the barrel of the device to discharge such Amucilage to the brush; to devise a novel construction and location for the stem which is used to operate the bar, the arrangement being such as to permit a portion of said stem to act as a grip to retain the device in the users pocket; and to provide novel plugging means for the mucilage outlet.

ith the foregoing in view, the invention resides in the novel features of construction and unique association of parts -hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawing which forms a part of this application.

Figure 1 is a side elevation of the device. Fig. 2 is a central longitudinal section it is carried in the 'users pocket.

Fig. 3 is a view similar to Fig. 2 showing the relation of parts when the device is t0 be used.

Fig. 4 is a side elevation, of the cylindrical head at the front end of the barrel and carrying the projectable and retractable brush.

Figs. 5, 6 and 7 are transverse sections on the planes indicated by the lines 5 5, 6-6 and 7-7 of Fig. 3.

In the drawing above briey described, the numeral 1 designates a tubular barrel whose front end is provided with a cylindrical head 3 secured in place by a rearwardly extending boss 4: which is threaded in the front end'of-the barrel tube. The front end of the head 3 is provided with a central discharge nipple 5 communicating with a bore 6 formed longitudinally through said head, the rear end of said bore being internally threaded for engagement with threads on the discharge neck 7 of a compressible tube 8, said tube carrying the mucilage and being by preference formed of lead or other appropriate pliable` material. It is intended that the tube 8 shall be sold independently of the remainder of the device, `in order that a new tube may be inserted' whenever necessary, the rear end'of the barrel being provided with the removable cap 9, for insertion of the tube.

The front end of the head 3 is provided with a forwardly extending cuff 10 which is spaced around the nipple 5, and a circular, mucilage applying brush 11 is mounted slidably on said nipple, with its periphery engaging said sleeve when the brush is projected. Normally, when the device is being carried in the users pocket, the brush 11 is retracted into cuff 10 as seen in Fig.

2 and a cap 12 then covers the entire front end ofthe article. By means of a finger piece' 13 extending outwardly through a slot 14; in the culi", however, the brush may be projected as in Fig. 3 to position it for use.

The inner end of the nipple 5 is normally -closel by a plug 15 located in the head 3 o' the barrel 1 and movable forwardly to close said nipple. For operating the plug, the latter is provided with a rear wardly extendingstem 16 which curves laterally and slides Ithrough the side ofthe head 3. A head 17 is formed o-n the rear end of the stem` 16 for pulling said stem rearwardly to remove the plug as seen in Fig. 3, and this head is normally located in la recess 18 in the head 3. Thel thumb nail may be inserted in the recess 18 for engagement with the head 17 to pull the stem 16 rearwardly when required.

' A longitudinal presser bar 19 is positioned inthe barrel 1 for compressing the tube 8, fiat longitudinal springs 20being secured. by rivets or the like 21 to said barrel 1, while securing means 22 fasten the other ends of the springs to the ends of the presser bar.` The springs 20 normally exert their tension 'to shift the presser bar 19- outwardly as in Fig. 2, and in order to force ,said b ar inwardly when themucilage is to 'be dlscharged (see Fig. 3), a stem 23 is connected by screw-threads or the. like to said presser bar and extends outwardly through the side of the barrel 1. The stem 23 is formed of inner and outer sections frictionally hinged together at 24, so 'that the outer section 25 may be folded inwardly against the barrel 1 as seen in Figs. 1 and 2, so that it will serve as a clip for 'securing the entire device in a pocket. rlhe Outer end of the stem section 25 is provided with a knob 26 which not only assists in forming the clip, but serves as means for pressing the stem inwardly to operate the bar 19, when the two stem sections are swung into alinement as in Fig. 3. rl`he stem 23 is ne-arer to the rear than to the front end of the presser bar, so that this bar is canted when forced inwardly,

f as seen in Fig. 3, thus forcing the mucilage forwardly in the tube.

Normally, the bar 19 is in its outermost position, the stem section is in its clipforming position, the plug' 15 is closed, the

' brush 11 is retracted, and the two caps 9 and 12 are in place, all as seen in Fig. 2. When the device is to be used, however, cap 12 is removed, brush l1 is projected, plug l5 is withdrawn, and stem 23 is operated to force the presser bar 19 inwardly as in Fig. 3. thus discharging a quantity of mucilage which may be applied by means of said brush 11. Whenever a new tube of mucilage is necessary, it may be easily inserted by removing the cap 9 and unthreading the head 3 from the barrel 1.

The device, as shown, is highly desirable yand may therefore be constructed in this manner, but within the scope of the invention as claimed, numerous minor changes may well be made.
